      A multiset allows multiplicity of elements. Hence, <!--l. 758--><math 
xmlns="http://www.w3.org/1998/Math/MathML" 
mode="inline">
  <mrow><mo 
class="MathClass-open">{</mo><mrow><mn>0</mn><mo

class="MathClass-punc">,</mo><mn>0</mn><mn>1</mn></mrow><mo 
class="MathClass-close">}</mo></mrow></math> is
